Question

Python: How I can check type of data being used in a python program and how many basic data types are supported ?

Answer 1

You may be looking for the type() function.

See the examples below, but there's no "unsigned" type in Python just like Java.

Positive integer:

>>> v = 10

>>> type(v)

<type 'int'>

Large positive integer:

>>> v = 100000000000000

>>> type(v)

<type 'long'>

Negative integer:

>>> v = -10

>>> type(v)

<type 'int'>

Literal sequence of characters:

>>> v = 'hi'

>>> type(v)

<type 'str'>

Floating point integer:

>>> v = 3.14159

>>> type(v)

<type 'float'>
